How do the girls use their knowledge and experience to help others stay safe at the beach?

I'm not sure if there is a book or story that is supposed to accompany this question.

But a few ways girls stay safe at the beach is with the buddy system. They stay in pairs or groups of people and they never go off alone with a stranger unless both of them consented.

just say it's your friend did it and you had no idea?

the students want to see the great sphinx of giza, which is very popular with tourists.
